Public bug reported: Steps to reproduce:
1. Open https://windy.com in Firefox or Chromium 2. Click on "Weather radar" in the right sidebar. 3. Click on the map and zoom in and out on some radar features with the mouse wheel for between 2 and 20 seconds. Expected results: - gnome-shell continues functioning Actual results: - gnome-shell becomes unresponsive to both mouse and keyboard and hangs indefinitely while consuming 100% of a CPU core. Symptomology: - Not related to GNOME Shell extensions. I have reproduced this bug after disabling all GNOME Shell extensions. - Happens on my machine 2 or 3 times a week with daily use, most consistently on https://windy.com. - Accessing a virtual terminal with e.g. Ctrl-Alt-F4 does not work. - SSH access still works, which is how I was able to get a backtrace. - Since this causes a hang, not a crash, it will not show up in apport crash reports.

Full backtraces are attached. Unfortunately debugging symbols for libgallium and libmutters libraries are not available so these backtraces are not as informative as they could be. Suggestions for improvement on this front are welcome. I have already tried using the Ubuntu debuginfod server.
